how does the squid know how bright to make its light organ? Does it detect (with eye or light organ) the brightness of the ocean surface above it? figure water pressure, convert it to depth, and then to required illumination level? something else?]]>

Hatchet fish might be the best examples, but squid have been known to do this before...

His blog is well worth visiting -- and worth adding to the daily routine for anyone who wants some good science writing.
